Abstract

[Background] Left subclavian artery (LSA) embolization is occasionally required to prevent type II endoleak in the thoracic endovascular aortic repair (TEVAR) procedure. This is a retrospective study comparing compressed Amplatzer Vascular Plug II embolization (CAE) and conventional coil embolization (CCE) in preventing retrograde flow into the aneurysmal sac through the LSA after TEVAR. [Methods] We retrospectively reviewed the records of patients who underwent CAE or CCE of the LSA during TEVAR from June 2013 to March 2016 in our hospital. The efficacy, safety and cost of each method were compared between two groups. [Results] Thirty patients underwent LSA embolization during TEVAR. Six CCEs in 6 patients were performed from June 2013 to November 2013, while twenty-four CAEs in 24 patients were performed from December 2013 to March 2016. Technical success was achieved in all patients in both groups. No embolization-related complications or type II endoleaks from LSA were recorded during the follow-up period in all patients. In both groups, all embolic materials were detected in the proximal portion of the LSA from the LSA orifice to the vertebral artery origin and no vertebral artery occlusions were detected. The mean compression ratio of AVP II was 58 ± 5.9% of predicted length of standard procedure. In the CAE group, one AVP II was sufficient to achieve complete LSA occlusion in all patients. On the other hand, multiple coils (10.2 ± 2.7) were used in the CCE group (P < .01), resulting in a significantly lower cost incurred in the CAE group (CAE: 129,000 JPY vs. CCE: 639,600 ± 140,060 JPY; P < .01). [Conclusion] The CAE is a useful and cost-effective procedure for TEVAR-related LSA embolization.

Abstract

【Background】 Bile leakage after hepatectomy is a common complication. The purpose of the present study was to retrospectively evaluate the usefulness of non-surgical management of bile leakage after hepatectomy, using 12-year data from a single center study. 【Methods】 Data from 15 patients (13 men, two women; mean age 67.1 ± 7.0 years) who had undergone nonsurgical management for bile leakage between January 2005 and November 2017 were retrospectively reviewed. 【Results】 We categorized bile leakage as central (n = 5) or peripheral (n = 10) leakage based on communication with the biliary tree. Percutaneous bile leakage drainage and/or endoscopic naso-biliary drainage (ENBD) (n = 2) or the rendezvous technique (n = 3) was successfully performed in five central-type cases, while all peripheral-type cases were treated with drainage alone; only one case required additional ethanol ablation. Bacterial bile cultures were positive in 11 cases and negative in four cases. The drainage catheters were removed after complete resolution in 13 cases (86.7%), while two patients with cases of peripheral-type leakage died due to cancer progression while the drain was in place. No case needed conversion to reoperation. The mean duration of drainage therapy in all cases was 210.1 ± 163.0 days (range 17?531 days), with 316.8 ± 180.8 days in the central type and 156.7 ± 131.5 days in the peripheral type; this duration was not significantly different (P = 0.129). 【Conclusion】 Non-surgical treatment is a minimally invasive and effective management strategy for postoperative bile leakage and the modality used depends on the type of bile leakage encountered.

Abstract

Portal vein stenosis, which results in serious clinical conditions such as gastrointestinal variceal bleeding and liver failure, is caused by hepatobiliary pancreatic cancer or major postoperative complications after hepatobiliary pancreatic surgery. In recent years, portal vein stenting under interventional radiology has been applied as a more useful treatment method for portal vein stenosis than invasive surgery. We herein report the successful use of a vascular stent for portal vein stenosis after pancreatoduodenectomy. A 66-year-old man with distal cholangiocarcinoma underwent subtotal stomach-preserving pancreatoduodenectomy with resection of the portal vein because of direct invasion to the main portal vein at our hospital. The portal vein was reconstructed without a venous graft. He developed jejunal bleeding near the pancreatojejunostomy on postoperative day (POD) 2. Although embolization of the responsible vessel achieved hemostasis, an intraoperatively inserted drainage tube was needed for a long period of time postoperatively because the embolized afferent jejunum was perforated. He was discharged on POD 39 after removal of the drainage tube. On POD 282, he was readmitted with melena and severe fatigue. Computed tomography revealed an obstruction of the reconstructed portal vein and varices at the hepaticojejunostomy site. We diagnosed variceal bleeding and performed percutaneous transhepatic stenting in the obstructed portal vein. The patient was discharged in good clinical condition on day 15 after stenting. In conclusion, portal vein stenting is a useful and less invasive therapy for portal vein stenosis.

Abstract

Background: Preoperative transcatheter arterial chemoembolization (TACE) is administered to improve long-term outcome after surgical resection of hepatocellular carcinoma (HCC). However, the survival benefit of preoperative TACE is controversial. We conducted a retrospective case-control study to evaluate the effect of preoperative TACE on prognosis., Methods: A total of 121 patients who underwent curative resection of HCC were divided into two groups according to whether they received preoperative TACE. We determined the control group ( n = 34) and TACE group ( n = 34) through propensity score matching. The primary endpoint of this study was overall survival, and the secondary endpoints were recurrence-free survival., Results: The overall survival rate and the recurrence free survival rate were significantly lower in the TACE group than in the control group ( P = 0.014 and P = 0.043, respectively). Furthermore, recurrence free survival within less than 2 years after resection was significantly worse in the TACE group than in the control group ( P = 0.035)., Conclusion: Preoperative TACE seemed to worsen the long-term outcomes of the patients who underwent surgical resection for the treatment of resectable HCC. Therefore, preoperative TACE should not be considered as a standard therapy in patients with resectable HCC.

Abstract

Background/aims: To evaluate the technical feasibility of the transfemoral approach using a 3.5-Fr catheter system for transcatheter arterial chemoembolization (TACE) in patients with hepatocellular carcinoma (HCC)., Methodology: This study included 81 patients with unresectable HCC who underwent transfemoral TACE using a 3.5-Fr catheter system without a sheath between August 2008 and June 2010. A 2.0-Fr microcatheter was used within a 3.5-Fr catheter in all cases. After completion of TACE, manual compression was applied to the puncture site for 5min, and patients were kept supine for 1h. The success rate and periprocedural complications of TACE were evaluated., Results: Transfemoral TACE with a 3.5-Fr catheter system was carried out in 103 transfemoral TACE sessions. TACE was performed for 103 subsegmental arteries, 19 segmental arteries, 13 lobar arteries, 8 right inferior phrenic arteries, 1 left inferior phrenic artery, and 1 inferior pancreatico-duodenal artery. Image quality in all hepatic angiograms using 3.5-Fr catheters was satisfactory. Technical success was achieved in 97 (94%) out of 103 procedures. In only 1 patient, it took 10min to achieve hemostasis. There were no periprocedural complications., Conclusions: Transfemoral TACE using a 3.5-Fr catheter system is technically feasible and enables early ambulation safely in patients with HCC.
